540s 'SError: { UnrecFIS }' on linux boot irregulary

I'am trying to understand the meaning and severe of a totally irregular appearing error during boot according to one of the SSDs connected to my NUC5I5RYH:

New SSD M.2 240GB INTEL SSDSCKKW24 (Modell: 540s), Firmware Version: LSF036C, checked without any errors with Intels SSD Tool (with W10), SMART values unremarkable.

SATA controller: Intel Corporation Wildcat Point-LP SATA Controller [AHCI Mode] (rev 03) (prog-if 01 [AHCI 1.0])

CPU: Intel(R) Core(TM) i5-5250U (Broadwell-U)

OS: ArchLinux, 4.8.12-3 x86_64 GNU/Linux

I testet reboot, boot after shutdown and boot after shutdown with power unplugged.

On every ca. fifth to tenth boot I get:

[code]

ata4: SATA link up 6.0 Gbps (SStatus 133 SControl 300)

ata4.00: ATA-10: INTEL SSDSCKKW240H6, LSF036C, max UDMA/133

ata4.00: 468862128 sectors, multi 16: LBA48 NCQ (depth 31/32), AA

ata4.00: READ LOG DMA EXT failed, trying unqueued

ata4.00: failed to get Identify Device Data, Emask 0x40

ata4.00: configured for UDMA/133

ata4: exception Emask 0x2 SAct 0x0 SErr 0x2000000 action 0x6 frozen t4

ata4: irq_stat 0x00000011, unknown FIS 00478027 a0000830 00000000 08000001

ata4: SError: { UnrecFIS }

ata4: hard resetting link

[/code]

Perhaps related to former June 2016 031C firmware release which provided the following changes:

* Corrected errant FIS causing BSOD when Write Cache disabled
